as far as I know Orgryte will miss 2 defenders(Johan Anergrund,Atli Thorarinsson) for sure,2-3 midfielders(Jeffrey Aubynn,Afonso Alves,Daniel Lohm,Martin Ulander)and one striker is probable(Christian Hemberg ).
Orebro will miss 1-2 midfielders(Mikael Steen,Fredrik Nordback )
So offence should be ok tonight for both teams.
